NH4I will completely dissolve in ammonium and iodide ions: of which I-is neutral and NH4+ is quite a weak acid (pKa = 9.25). (The molar standard solution of NH4I will have pH approx. 4.6).
1 Hence, there is more concentration of H+ ions in solution, which results in the solution being acidic. 2  Salts formed from weak acids and strong bases (e.g. NaHCO3 â NaOH + H2CO3; Na2CO3 â NaOH + H2CO3) The solutions are basic (i.e. the concentration of OH-ions is more than that of H+ ions). 23. 2  Salts formed from strong acids and weak bases (example, NH4Cl â HCl + NH3) Solutions of these salts are acidic (i.e. conc. of H+ is more than that of OH-). 3  The OH-ions are attracted more to the positive ions of the salts than the H+ ions are attracted to the negative ions.
